Siemens 6ES7960-1CB00-5AA5 Fiber Optic Cable

Technical Specifications Overview

Functional Overview and Optical Connectivity

This fiber optic cable provides a reliable physical link for Siemens automation networks. It connects PROFIBUS and PROFINET devices over extended distances. The 6ES7960-1CB00-5AA5 enables high-speed data transmission with complete electrical isolation. Moreover, optical communication eliminates ground loop issues between remote stations. This feature proves essential in large industrial facilities with distributed control systems. The cable supports both point-to-point and ring network topologies. Consequently, you can design redundant communication paths for critical applications.

Construction and Optical Performance

The Siemens 6ES7960-1CB00-5AA5 features a duplex multimode fiber with 62.5/125 µm core/cladding dimensions. This fiber type offers excellent light-gathering capability for industrial distances. The cable exhibits low attenuation of ≤ 3.0 dB/km at 850 nm wavelength. Additionally, the bandwidth exceeds 160 MHz·km, supporting high data rates. The orange PVC jacket provides both visibility and flame retardancy. The cable also resists oils, solvents, and common industrial chemicals. This robust construction ensures reliable performance in demanding factory floor environments.

Connector Design and Termination

The cable terminates with two BFOC connectors on each end. These bayonet-style connectors provide secure, quick-disconnect coupling. The BFOC design ensures positive locking and prevents accidental disconnection. Furthermore, the connectors feature precision-polished ceramic ferrules. These ferrules minimize insertion loss and return loss for signal integrity. The connectors also include protective dust caps for storage. This protection prevents contamination of the optical surfaces during installation.

Physical Attributes and Installation Parameters

The cable measures exactly 5.0 meters in length for convenient cabinet-to-cabinet connections. Its 6.0 mm outer diameter offers flexibility while maintaining durability. The minimum bending radius of 60 mm prevents fiber stress during installation. For dynamic applications, maintain a 120 mm bending radius. The cable weight of approximately 0.05 kg per meter simplifies handling. The maximum tensile strength of 200 N allows reasonable pulling tension during routing. Additionally, the crush resistance of 1000 N/100 mm withstands incidental foot traffic.

System Integration and Compatibility

This cable works seamlessly with Siemens PROFIBUS optical link modules. Typical pairings include the OLM (Optical Link Module) series for network extension. The 6ES7960-1CB00-5AA5 also interfaces with ET 200 distributed I/O stations. Furthermore, it connects S7-400 controllers to remote PROFIBUS segments. The cable supports data rates up to 12 Mbps over the full 5-meter distance. This performance meets the demands of most industrial automation applications. Install the cable in cable ducts or cable trays for proper protection.

Environmental Robustness and Standards

The cable operates flawlessly in temperatures from -40°C to +85°C. Storage conditions range from -55°C to +90°C for flexibility. The unit also complies with IEC 60793 and PROFIBUS guidelines. This dual compliance ensures interoperability with standard industrial networks. Use the cable only in dry, indoor environments unless additionally protected.
